The logic added in r343287 to avoid false-positive sum-of-child-bandwidth check errors for HFSC queues has a bug in it that causes the upperlimit service curve of an HFSC queue to be pulled down to its parent's linkshare service curve if it happens to be above it. Upon further inspection/reflection, this generic sum-of-child-bandwidths check does not need to be fixed for HFSC - it needs to be skipped. For HFSC, the equivalent check is to ensure the sum of child linkshare service curves are at or below the parent's linkshare service curve, and this check is already being performed by eval_pfqueue_hfsc(). This commit reverts the affected parts of r343287 and adds new logic to skip the generic sum-of-child-bandwidths check for HFSC.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
